💅 omap2_prm_assert_hardreset(9)

okay so this one lives in the Kernel API Manual bestie, and it's literally about slamming the reset line on a submodule. let's get into it 🎀

---

✨ NAME ✨

omap2_prm_assert_hardreset — assert the HW reset line of a submodule 🔥

---

🌸 SYNOPSIS 🌸

int omap2_prm_assert_hardreset (u8 shift , u8 part , s16 prm_mod , u16 offset );

---

🦋 ARGUMENTS 🦋

• shift — the register bit shift that corresponds to the reset line you wanna assert, like that's your specific line bestie 💅
• part — the PRM partition. lowkey ignored for OMAP2 🙈
• prm_mod — the PRM submodule base (e.g. CORE_MOD) 👑
• offset — the register offset, also ignored for OMAP2 ✨

---

💖 DESCRIPTION 💖

so some IPs — like dsp or iva — contain processors that require a HW reset line to be asserted / deasserted in order to fully enable the IP. it's giving "you can't sit with us until you reset" energy 😭

these modules may have multiple hard-reset lines that reset different 'submodules' inside the IP block. the way that this function just places the submodule into reset. periodt. 🫶

it returns 0 upon success, or -EINVAL upon an argument error 💀
